Famous quotes containing the word facts:

    Birth, and copulation, and death.
    That’s all the facts when you come to brass tacks:
    Birth, and copulation, and death.
    I’ve been born, and once is enough.
    You dont remember, but I remember,
    Once is enough.
    —T.S. (Thomas Stearns)

    “Now what I want is, Facts. Teach these boys and girls nothing but Facts. Facts alone are wanted in life. Plant nothing else, and root out everything else. You can only form the minds of reasoning animals upon Facts: nothing else will ever be of service to them.”
    Charles Dickens (1812–1870)

    Whilst Marx turned the Hegelian dialectic outwards, making it an instrument with which he could interpret the facts of history and so arrive at an objective science which insists on the translation of theory into action, Kierkegaard, on the other hand, turned the same instruments inwards, for the examination of his own soul or psychology, arriving at a subjective philosophy which involved him in the deepest pessimism and despair of action.
    Sir Herbert Read (1893–1968)
